Design and Simulation of Controller for Chaotic Duffing Oscillator

摘要

Controlling chaos in Duffing Oscillator with bounded period parameter is studied in this paper, proposes sliding mode variable structure control algorithm and design controller to eliminate chaos in Duffing Oscillator. During the sliding mode phase, fuzzy rule is pressnied. The analysis and simulation results show that the fuzzy sliding mode variable structure controller can control the chaotic oscillation of the Duffing Oscillator effectively, the control speed is greatly enhanced and the high frequency chattering in sliding mode variable structure control is effectively controlled comparing with the traditional sliding variable structure controller.
